A particular brand of gasoline has a density of 0.737 g/ml at 25 ∘c. how many grams of this gasoline would fill a 14.1 gal tank?

Density is defined as the mass per unit volume,

mass of the solution is therefore

mass = density x volume

1 gal = 3785.41 mL

therefore 14.1 gal = 3785.41 x 14.1 = 53 374.3 mL

mass of gasoline required = 0.737 g/mL x 53 374.3 mL

mass of gasoline required to fill the tank - 39 337 g = 39.3 kg

39.3 kg of gasoline is required
